SN74HCT139PWR Dual 2-Line to 4-Line Decoders/Demultiplexers

The SN74HCT139PWR from Texas Instruments is a versatile and high-performance integrated circuit designed to solve decoding and demultiplexing needs in a wide range of digital applications. This device features two independent 2-line to 4-line decoders/demultiplexers in a single package, allowing for efficient use of board space and system resources.

Each section of the SN74HCT139PWR operates as a 2-line to 4-line decoder or a 1-to-4 demultiplexer without external gating. The active-low enable (G) input can disable the device so that all outputs are high. When the device is enabled, each decoder accepts two binary weighted inputs (A0 and A1) and, when activated, provides four mutually exclusive active-low outputs (O0 to O3).

Key Features:

• Logic Type: Dual 2-Line to 4-Line Decoder/Demultiplexer
• Supply Voltage Range: 4.5 V to 5.5 V
• Operating Temperature: -40°C to 85°C
• Output Current: High/Low: 4 mA / 8 mA
• Package / Case: TSSOP-16
• Logic Family: HCT
• Propagation Delay Time: 18 ns (typical)
• Mounting Type: Surface Mount

The device is fabricated with high-speed CMOS technology which ensures minimal power consumption and high noise immunity. The SN74HCT139PWR is compatible with TTL logic levels, allowing it to be used with older logic families while benefiting from the advantages of CMOS technology.

With its compact TSSOP-16 package, the SN74HCT139PWR is ideal for use in systems where space is at a premium. Common applications include computers, control systems, data communications, and other digital systems that require a high-density decoding or demultiplexing solution.

By providing reliable performance and a broad operating temperature range, the SN74HCT139PWR is a preferred choice for designers looking for a robust and efficient solution to their digital logic requirements. Its ease of use and integration into existing systems make it an excellent choice for both new designs and upgrades to existing systems.
